Write a program to print “Hello World!” to the LCD (Liquid Crystal Display) and shows the time in seconds since the Arduino was reset.

#include <LiquidCrystal.h>

// RS, E, D4, D5, D6, D7 pins of LCD connected to Arduino
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  lcd.begin(16, 2);       // Initialize 16x2 LCD
  lcd.print("Hello World!");
}

void loop() {
  lcd.setCursor(0, 1);   // Move cursor to second row
  lcd.print("Time: ");
  lcd.print(millis() / 1000); // Time in seconds
  lcd.print(" sec");
  delay(1000);           // Update every second
